BACnet Gateway

BACnet to M-Bus
BACnet to Modbus
Modbus to MBus

The Kara BACnet gateway integrates M-Bus meters and Modbus
devices into BACnet infrastucture. It represents a BACnet Device and
several BACnet objects. M-Bus meters are converted to BACnet Analog
Inputs. Modbus Input discrete and Coils are converted to BACnet
Binary inputs and outputs respectively and Modbus Input/Holding
Registers and converted to BACnet Analog input and output objects.
The gateway supports both BACnet/IP and BACnet/Ethernet
The connection to BACnet is done over Ethernet LAN BACnet/IP or BACnet/Ethernet. To connect the
gateway to M-Bus you need a Level Convertor to convert the EIA-232(
optional EIA-485) connection to M-Bus physical Bus.
Gateway as well can converts M-Bus meters to Modbus Holding registeres

M-Bus Level Converters

MBus-LC-10
MBus-LC-60

MBus-LC-10 and Mbus-LC-60 converters are transparent converters from RS232 to Mbus interface.
On MBus side they work as MBus master and enable to connect maximum 10 / 60 standard MBus receivers
(slaves) respectivily.
Mbus-LC-60 has an embedded MBus Slave input and can operate as MBus signal buster.
They can be used with all devices equipped with MBus interface like: heating energy meters,
electric energy meters, data recorders and many others with MBus interface.
